Had the car in with Chris Gray for a suspect misfire (which he sorted, new plugs ) and told him about my aircon problems. Me being slightly dim, did not read his letterhead because he is an A/C specialist as well!
He had a look, and it turns out my A/C fans are seized There are two on my car, one has a small belt to power the other and they have stopped working. He suspects a hole in the condenser as well, the ultraviolet will confirm.
No money left this month so will have to wait till HMG pays again, but will drop it into Chris and get it sorted. He confimed the company I was looking at were his choice as well.
